Features of coastal microbial communities in seas with different geographical locations

The present study aims to investigate the responses of microbial communities to sewage discharges in coastal ecosystems of the Caspian Sea, Absheron peninsula and the Red Sea near Jeddah Saudi Arabia. The article describes the general physical–geographical locations, climatic conditions, the degree of the salts of the waters of the seas, the presence of heavy metals, their concentration, the degree of exposure to anthropogenic impact.

The species and quantitative composition of microorganisms in the water of the seas were studied, a comparative analysis of data obtained, problems and ways of their solution were carried out.
